✦ Synopsis

We report the generation of high-power, quasi-continuous wave red-light up to 11.5 W in a 4-cm LiB 3 O 5 crystal with intracavity frequency-doubling of two compact and simple side-pumped Nd:YAG laser modules under a repetition rate of 3.5 kHz. The beam quality of M 2 value is 15 ± 3 in both directions. The short-term stability of the red-light source is better than 1% at an output of 9 W. Other characteristics of the red-light laser were also experimentally studied and presented.
